how to......

[cleversod]

Hi Everyone. Have just bought a Commodore off Phil, it's gorgeous, and waiting for a P2 Pulsar to arrive ( excited? not kidding!).
Now...please dont shoot me down in flames, but, what I'd really like is some nice clear instructions on how to get the backs off and change the batteries on both watches. Bit unfair to keep sending the to Phil to change them. Now, Im a medical man, good with my hands, and well aware and agree with "only use the right tools for the job".. but can someone spend a few minutes to post for a complete and addicted newbie like me?
I dont mind rolling up my sleeves and getting my hands dirty, I specialize in minor surgery so I do close and intricate, but dont want to scratch or damage either watch.
Thanks
John

I assume the CBM will be a snap on back cover, so for that you just need a case knife, these are readily available on eBay, or just use an old blade from a Stanley knife. For the Pulsar look for eBay user barbie9 he sells the correct tools for opening Pulsars, they're very easy to open with the right tool, but very tricky with any other case opening tool due the unique locking ring, it's the only type I know of that has only 4 teeth.

I make a good replica of the Jewelers' Case Wrench for the Time Computer watches. This is a cylindrical tool that engages all four of the notches in the locking ring simultaneously. It is virtually impossible to damage either the caseback or ring using this tool. The flat wrench engages only two of the notches, and it is not difficult to slip and cut a nasty gash across the back of your prized Pulsar. I see Pulsars all the time with these "oops" marks, some of them quite disfiguring. I have a set of the flat wrenches, but never use them...I consider them a Pulsar collectible...not a practical tool. Any interested collectors....PM me and I will send pics and prices. I discovered I had to make these; I was running into too many watches that had been sealed for many years, and nothing else would permit the application of sufficient torque to get them open without doing serious damage. I have yet to encounter a watch I could not open with this tool.

Hi.

I left a previous post in the Workbench section regarding Bruce's wrench, but to summarize, once you use one of these you will never go back to another (lesser) style. I agree with Bruce's comments on the flat, two prong wrench.

Bruce's wrench works extremely well.
